Configuring an ISATAP tunnel
Follow these guidelines when you configure an ISATAP tunnel:
• You do not need to configure a destination address for an ISATAP tunnel, because the destination
IPv4 address is embedded in the ISATAP address.
• Because automatic tunnels do not support dynamic routing, configure a static route destined for the
destination IPv6 network at each tunnel end. You can specify the local tunnel interface as the egress
